ENVELOPE.

Application filed January 2, 1924. Serial No. 683,900.

My invention relates to envelopes or paper bags and more particularly to that type which is provided with means, in the nature of a handle, enabling the envelopeor bag to be conveniently carried.

Heretofore envelopes and paper bags have been provided with carrying handles, but it has been found in practice that such envelopes or bags are not entirely satisfactory,

since when they are carried they tend, under the weight of their contents, to open, or if opening is prevented, they are more or less complicated in design, diflicult to close and have reduced capacity.

5 Now it is the object of m invention to provide an envelope or paper ag which will be adapted to be carried by a handle which will not open when carried and at the same time one which will be extremely simple to close and .made ready for carrying.

Further objects of my invention are to provide an envelope or bag which will be readily blanked out without waste of stockand which will be efficient in service.

Having now indicated in a general way the nature, purpose and advantage of my invention, I will proceed to a detailed description thereof with reference to the accom-' panying drawings in which I have illustrated a preferred embodiment and in which: I

Figure 1, is a plan view from the rear of the upper portion of an envelope embodying my invention, the envelope being open.

Figure 2, is a View similar to that of Figure 1, the envelope being closed.

Figure 3, is a view similar to that of Figure 1, the envelope being secured in closed position.

Figure 4, is a sectional view on llne 4.-4, Figure 3.

Figure 5 is a plan view of the upper portion of the back of an envelope embodying a modification of my invention.

Figure 6 a via-W of thereairof an velope similar to that of Figure 5, partially closed.

Figure 7, is a view similar to that of Figure 5,. with the envelope in fully closed posi tion.

Figure 8, is a sectional view on line 8-8, Figure 7.

Figure 9, is a sectional view on line 99, Figure 7.

The envelope, as illustrated in Figures 1-4, and it will be understood that my invention is equally applicable to containers which would be called bags, is formed from a single blank folded to form a front wall a and a back wall 6, the front and back being joined together along the edges as is customary.

The front wall a is made longer than the back wall to form a closing flap 0 adapted to be folded over against the outside of the back wall]; and form a closure for the open end of the envelope.

The flap 0 is slit to form a handle 01 in such a manner as to leave on the flap adja 1 cent to line of fold the opposite projections e, c. The handle is provided with angularly extending slits 00, m, and a slit 1, extending horizontally between intermediate points on slits 02, m to form. a pair of tabs, f, f.

The back wall I) of the envelope is provided with two spaced curved slits extending downwardly from its upper edge forming the oppositely extending projections or ears, The front wall is provided with two vertical slits, 79, 79, positioned in relation to the slits forming the projections g, 9, so as to be substantially chords of the curves thereof.

The operation of the embodiment of my invention shown in Figures 1% will, it is believed, be obvious from an inspection of the figures.

After the article or articles desired to be carried in the bag are placed therein, the flap c, is folded over against the outside of the hack 5, leavin the handle extendin beyond the bag e projestiens e, e on, the

. duced a forms a surface for the lingers, while the.

lower tab serves as a closure for that portion. of the, open end ofthebag below the handle and not closed'by the flap c, as will be seen from an inspection of Figure 8.

illustrated a modification of my invention, the front and back walls of an envelope are indicated bythe'letters a. and b" respectively.

The handle a is-joined-integral"withthe front. walland slit.- angularly and horizontally to formthe tabs f, f.

T-he front and back. walls-are extended upward beyond the base of the handle to formflaps h, It, adapted to be folded over against the back wallv on a line with the base *ofthehandles to form a closure'forthe en- The edgesof the flaps h, adjacent velope; thiehandleextend toward each other beyond the; outer edges of the handle and are out at an angle, thus forming projecting portions or. ears, 1', i. 1 I

The operationof the modification of FiglVhen the bag is filled,the flaps h, it, are folded down against the. back wall.

openingof the bagand the projection or ears 2', 2' will-engage behindthe handle as shown in Figures? and 8,"thus elfect-ively locking the flaps in closed". position.v grasping the handle the tabs f", f, will be displaced and serve as a closure forithe openingof the bag within the confinesi'of the handle and as a surface for the fingersas described in connection with Figures 1%.

As a result'of my invention there isproduced a bag which may be-etfectivelyclosed and kept closed and easily carried from place to place, at the same time there is-pro- Having now fully described my invent-ion, what I claim and desire to protect by Letters Patent is:

1. An envelope comprising front and" back walls joined along three sides, a flap formed by an extension of one of said wallsu down against the opadapted to be folded flap posits wall and a handle formed in said ada-ptedto :liein the planeof the walls,.said

That part of-the flaps formed in the -wall= opposite to. that against which the flaps are folded will close-the bag which may be easily=and ecoi nomically produced and readily made use of;

handle being slit horizontally and angularly to form tabs adapted to be bent on parallel lines to form upwardly and downwardly extending tabs to provide a surface for the fingers and a closure for that part of the envelope beneath the handle, respectively;

2. An envelope comprising front and back walls, a flap formed by an extension of one of said walls, a handle formed in said flap, one of said walls being slit downwardly ad jacent to the edges of the handle, and oppositely extending projections formed in said flap and in. one, of said walls, adapted.

when the envelope is closed. to be extended walls, a flap formed by an eXtension of one Referring now to Figures 59 in WhlCh 1s tions and oppositely extending projections formedin said flap and adapted: to overlie saidrprojcctions in one of said. walls when:-

the envelope is closed; said overlyingnprose jection being 1 adapted to be extended through. said slitted.

4: :Anienvelope comprisingfront and back walls, a. flap. formed bywan extension: of said front-wall, a handle formed in saidw-flap,

oppositely."uextendingf arcuate" projections 7 formed in saidfiap adjacent. to the base of the said handle, oppositely extending projections formed by arcuate' 'slits insaid back wall adjacent to the; upper edge thereof and downwardly extending slits in saidfront wall, said projections in saidflap and-said back :Wall be ng adapted to overlie when: said envelope is; closed-=and beextended through said downwardly eXtending'slits-in said I frontwall to: secure said envelopev in closed position. 1

5.

6,: An envelopercomprising front dlldabttfik walls, a closure flap formed as an extension of one of said Walls and arranged to be folded over the outer side of the other of said Walls, a projection formed in the flap, and a. similar projection formed in the well over Which the flap is foldable and aligning with the first projection When the flap is folded, the Wall carrying the flap being slitted for the reception of both projections to form a closure for the envelope.

In testimony of Which invention, I have hereunto set my hand, at Philadelphia, Pa. on this 27th day of December, 1923.
